【摘要】：利用高密度电法、微波测湿和热红外成像等无损检测手段,结合便携式离子色谱的现场分析和温湿度监测等方法,从水汽和盐分2个角度开展对隆兴寺摩尼殿扇面墙壁画病害区域的综合调查,研究盐害的主要成因。结果表明,壁画支撑体和地仗中的水汽主要来源是空气中的水汽和大气降水,毛细水作用通道的存在和区域温差导致的水汽运移速度加快为水分在文物本体中的活动创造了条件,支撑体和地仗中较高含量的易溶盐是病害产生的根本原因,高湿、高盐是壁画病害区域的典型特征。
[Abstract]:By means of high density electrical method, microwave moisture measurement and thermal infrared imaging, combined with portable ion chromatography field analysis and temperature and humidity monitoring, From the point of view of water vapor and salt, a comprehensive investigation was carried out to study the main causes of salt damage in the mural area of Moni Temple, Longxing Temple. The results show that the main sources of water vapor in the mural support and ground battle are the vapor in the air and the precipitation in the atmosphere. The existence of capillary water action channels and the acceleration of water vapor migration caused by regional temperature difference create conditions for the movement of water in the body of cultural relics. The high content of soluble salt in support and ground battle is the root cause of the disease. High salt is a typical feature of mural disease area.
